SPECIFICATION forming` part of Letters llatent N o. 705,290, dated July 22, 1902.

Application iiled May 1 3 l 9 01.

' lo belts, and has for its object to provide certain improvements in connection with the headwheel about which the filled 'buckets pass.

My improvements are illustrated in the ac-j companying drawings, wherein- Figure l is avertical section. Fig. 2 is an end elevation of the device shown in Eig.' 1. Like parts are indicated by the same letter in both figures. f A

It willA be understood that I have simply.v 2o shown a portion of the device, and the'relnaining parts, including the remainder of the4 chain belting, the buckets, the conveyer, the chutes,the wheels,and the supporting-frames, I do not deem it necessary to show, as they form no part of mypresent invention.

A A-are the links,which taken together form a link belt, upon which at the pivot-pins B B are' secured the buckets C, adapted each to receive a proper charge of coal'or other 3o material D. g

E is asprocket-wheel, which may be called the head-wheel. There are two of these y wheels, one for each set of links, and the buckets pass between such twol wheels. These sprocket-wheels are mounted on a shaft F..

On the shaft F and rotating therewith; and therefore rotating with ythe sprocket-wheels and moving with the chain of buckets, is a spool-like structure consisting of the sides 4o G G and containing a series of pockets formed between the sides and by the metal plates H H, which in this case are arranged tangentially to a small circle about the center of the shaft F and which extend each from its intersection with the next behind it to the 'circumference of thecircle, which is preferably substantially coincident with the are of a circle described byfthe innermost portions of the buckets as they pass around over the sprocket- 5o wheels.` -1t,-will be.,understood that the size SerialrNo. 59,931. (No model.)

several parts which go to form the pockets may be greatlyvaried without departing from the spirit ofA my invention.

J is a chute, preferably having the lip K inwardly y projecting between the sprocketfwheels and`beneath the vertical tangent to -the circle described by the spool as it rotates.

L VL represent'the charges of coal or other material in the pockets, and M the coal in the process of being'disch'arged down or toward thechute. There is no necessary relation between 1the length of the arc formed at the outside of the rotating pocket and the length of a bucket,'thou'gh it would be desirable vto so adjust these parts with reference to each other that projecting objects, like the lump `of coal, (indicated at D,) would not engage the outer endv of one of the. plates H as it rose toward its horizontal position, for in that case there would be danger of injury to the parts .inthe caseof'heavy and hard lumps of coal or other such material. It will'be possible to so adjust these several parts as that the 'outer extremity of the plate H could extend beyond the circumference of the circle referred to and take under the inwardly-projecting en d or edge of the bucket; but the con- -struction which/I have preferred is the one shown in the drawings.

The use and operation ofmy invention are as follows: f

I have arranged the parts so that'two buckets discharge into each succeeding pocket; but of course this is not a necessary form of construction. As thesprocket-wheels rotate on or'with the shaft F the chain belt is carriedY forwa'rdlyand upwardly in the direction indicated by the arrows,and the buckets filled The top bucket, as shownand the lengths and arrangements of these .f

pocket L, and the next bucket to the left has emptied a part of its loadand isf about tol f etsthe 'next twobuckets will in due course of ti me deposit their loads in their associated pocket. The upper pocket to the right is discharging its load into the chute, the preceding pocket having already discharged its entire load into the chute. From the chute the material can be carried to any desired point. In such an apparatus or with such an arrangement of parts the material in the ascending buckets though in large and irregular lumps and projecting beyond the face of the buckets is nevertheless not in danger of causing injury to the parts by its engagement with the receiving or supporting parts associated with the head-wheels. Again, all fixed guides, chutes, or associated parts are dispensed with by the substitution of the pockets, and these pockets become not means for holding the material in the buckets as the buckets pass around the wheels, but they actually receive the material from the buckets, which buckets are thus entirely emptied of their load before they pass over the vertical line. At the same time the receivingpockets discharge the load into the chute, and this they easily do without any danger of discharging the coal back into the machinery or apparatus, for the chute or its lip can be placed at any desired position under the rotating pockets. There is no danger of the material falling back into the machinery or upon the lower buckets, because it is at all times securely retained in appropriate receptacles, first the buckets and then the pockets, until it has been discharged into the chute, whence it is led by proper ways to the bins for use.

As shown in the drawings, each pocket is the space intervening between two of the plates H H on the ascending side. The lower plate forms the receiving-bottom and the upper plate the top; but when this pocket has been carried around and is on the descending side the first-named plate forms the top and the second one the discharging-bottom. The buckets are placed as closely together as possible, as indicated in the drawings. This is what is meant by placing them in contiguity, and one of the problems solved by me was the coperation of rotating pocketsy with a series of such buckets thus in contiguity or close relation to each other. The result is to form, as it were, a continuous stream of material, and the greatest possible amount of material is moved for a conveyor having a given cross-section in the ascending branch. As indicated in the drawings, these buckets open inwardly or toward the pockets; otherwise they could not empty into the pockets, and this presented another diiiiculty to be solved by my invention and one which is suggested above. If the buckets open inwardly, then in the case of large lumps, as shown and described, they project beyond the buckets and into the line of rotation of the pockets,and the diiculties flowing from these conditions have been solved by my present invention.

As shown, for example, in Fig. 1, the pockets and buckets are so spaced and timed that the bottom of the pocket follows the bottom of the bucket, and hence any projecting pieces in the buckets will project into the pockets and cannot come into contact with the bottom of such pockets so as to injure them.
